If they still made a wagon/hatch WRX, I would definitely be interested, but they haven't done that in a while. Honda has a new hatchback, but it's all boy-racer with not much umph, and the top trim level isn't out yet.
As for "Bluetooth streaming", I never use it (on our cars). Maybe newer protocols are OK, but older ones were bad. I always plug my phone into our cars to stream from the phone... plus it charges! Although, it usually works with just the USB port -- having to also use an adapter and AUX port is a bit of a hack. I don't mind using my phone or standalone GPS for GPS. So, hopefully it won't be so tragic, even though a GPS stuck somewhere may look tacky. It does kind of counter the "luxury" image.
